enzymes of isolated brush border membrane of cotugnia digonopora, and their insensitivity to anthelmintics in vitro.purified brush border membrane of cotugnia digonopora showed the presence of a number of phosphohydrolases. among these, alkaline phosphatase was extremely active. other enzymes such as glucose-6-phosphatase, fructose-1,6-diphosphatase, camp-phosphodiesterase, 5'-nucleotidase and adenosine-triphosphatase were also active. observations were made on the activities of various atpases; whereas the enzyme was activated by ca++ and mg++ in an additive manner, its sensitivity to ouabain was negligible. ...19852996211
embryos and embryonic envelopes in eggs of two cyclophyllidean cestodes.membranes and envelopes around the embryos in eggs of cotugnia digonopora and raillietina (r.) echinobothrida have been studied in detail. this is the first study giving details of the egg-shell of a cotugnia species. there are 3 membranes and an equal number of envelopes around the embryos in eggs of c. digonopora , while there are 2 membranes and only one envelope in case of eggs of r. echinobothrida . noteworthy is the presence of a membrane in eggs of c. digonopora , termed "middle capsule", ...19846539089
cotugnia digonopora: carbohydrate metabolism and effect of anthelmintics on immature worms.cotugnia digonopora consumes, in 24 hours, glucose equivalent to 38% of its body-weight and converts it into metabolites. the krebs' cycle is insignificant in the breakdown of glucose because very little co2 is formed. ether-extractable acids account for most of the consumed sugar, confirming that metabolism is predominantly anaerobic. glucose is assimilated as glycogen rather than as nucleic acids, lipids and proteins. niclosamide, praziquantel and mebendazole strongly inhibit uptake of glucose ...19846715861
unsaponifiable lipids of cotugnia digonopora and raillietina fuhrmanni (cestoda: cyclophyllidea).unsaponifiable substance in cotugnia digonopora and raillietina fuhrmanni (cestoda: cyclophyllidea) was 6.3% and 7.5% respectively of the total lipid content. on characterization of the unsaponifiable fraction, cholesterol was found to be 90% and 93% respectively in the two cestodes. a search for friedelin was negative.19807364346

helminth parasites in the intestinal tract of indigenous poultry in parts of kenya.a study was carried out on 456 indigenous poultry intestinal specimens from various towns in kenya to determine the occurrence and distribution of helminth parasites in the intestinal tract of the birds. of the specimens examined, 414 had parasites whereas the remaining 42 had none, which is an infection rate of 90.78%. the main species of helminths found in the intestines were raillietina sp. (47.53%), heterakis gallinarum (21.33%), ascaridia galli (10.03%), strongyloides avium (9.96%), choanot ...200415214699
tapeworms of rock dove and domestic chicken in taif area, saudi arabia.the present study aimed to identify the tapeworms that parasitize the rock dove columba livia palastinae and domestic chicken gallus gallus domesticus in taif governorate, saudi arabia. a total of 115 rock doves and 105 domestic chicken have been examined. birds were brought in from the wells and farms inside and outside the city of taif. in rock doves, the percentage of infection was recorded as cotugnia digonopora 5.21%, hymenolepis carioca 10.43%, raillietina echinobothrida 27.82%, raillietin ...201223469626
biodiversity and prevalence of parasites of domestic pigeons (columba livia domestica) in a selected semiarid zone of south khorasan, iran.five species of nematodes and cestodes were collected from alimentary canals of pigeons: the nematodes were two species: ascaridia colombae (16.66%) and hadjelia truncata (1.96%), while the cestodes were cotugnia digonopora (13.79%), raillietina magninumida (18.62%) and raillietina achinobothridia (32.35%); fecal examination revealed: eimeria spp. (40.19%) and cryptosporidium oocysts (2.94%); and blood smears showed: haemoproteus cloumbae (47/05%); in mouth, throat and larynx: trichomonans galli ...201222081317
energy metabolism in cotugnia digonopora and the effect of anthelmintics.incorporation of 32pi into organic phosphate by mitochondria of cotugnia digonopora was supported maximally by malate. fumarate and succinate induced lower but significant production of atp. pyruvate, alpha-ketoglutarate and oxalacetate proved to be poor substrates and citrate and isocitrate had no effect. a net phosphorylation of approximately 2 mol of adp was observed for each mol of co2 liberated from malate or succinate. in contrast, with pyruvate, in spite of a high rate of decarboxylation, ...19846749180
[tapeworm fauna of gallinaceans (galliformes) of vietnam].131 specimens of 3 species of galliformes from vietnam were investigated (gallus gallus dom., g. g. jaboruillei, francolinus pintadeanus and lophora nycthemerus). in them 9 species of cestodes were found as follows: davainea proglottina (davainea, 1860), cotugnia digonopora (pasquale, 1890), raillietina tetragona (molin, 1858), r. echinobothrida (megnin, 1880), skrjabinia cesticillus (molin, 1858), paroniella tinguiana tubangui et masilungan, 1937, amoebotaenia cuneata (linstow, 1872), echinolep ...1978733321
